No Display when I connect the Tesla c1060 GPU to my CPU

Dear All,

I am having trouble installing the CUDA toolkit 5.5 on my UBUNTU(64 bit) system. The main cause of the problem is that there is no display on my computer as soon as I connect the above mentioned GPU to my system. The system works perfectly when there is no GPU attached. I am having Ubuntu 10.04(64 bit) operating system. My processor is Intel® Pentium® Dual CPU E2200 @ 2.20GHz and motherboard model is Intel DQ45CB. I have 8GB memory installed.

Any help or guidance will be helpful.

Thanks in Advance
